Txawm hais tias kub-melt nplaum zaj duab xis thiab nws tus kheej-nplaum yog tib yam khoom, cov lus nug no zoo li tau plagued ntau tus neeg. Ntawm no kuv tuaj yeem qhia rau koj kom meej tias kub yaj nplaum zaj duab xis thiab tus kheej nplaum tsis yog cov khoom nplaum tib yam. Peb tuaj yeem nkag siab luv luv ntawm qhov sib txawv ntawm ob los ntawm peb yam hauv qab no:
1. Qhov sib txawv ntawm kev sib khi lub zog: Kub yaj cov nplaum zaj duab xis yog cov nplaum nplaum thaum tshav kub kub. Nws yog lub xeev ruaj khov nrog kev ua haujlwm ruaj khov ntawm chav tsev kub thiab tsis muaj viscosity.
Nws yuav nplaum tsuas yog thaum nws melted, thiab nws yuav solidify tom qab txias, tsis stickiness, me ntsis zoo li yas. Muaj ntau hom kub yaj nplaum zaj duab xis, thiab ntau hom kub yaj nplaum zaj duab xis muaj cov ntsiab lus melting sib txawv, uas feem ntau npog qhov kub thiab txias, nruab nrab kub, thiab kub. Self-adhesives yog tiag tiag self-adhesives. Lawv nplaum nyob rau hauv chav tsev kub. Lawv kuj muaj ib tug melting point, tab sis feem ntau lub melting point yog tsawg heev, txog 40 degrees. Qhov qis ntawm qhov melting point, qhov qis dua lub zog sib txuas tom qab txias, uas kuj yog ib qho tseem ceeb vim li cas cov nplaum nplaum nws tus kheej yog yooj yim dua los tsim kua muag tom qab pasted.
2 Qhov sib txawv ntawm kev tiv thaiv ib puag ncig: Nws yuav tsum tau hais tias kev tiv thaiv ib puag ncig ntawm kub yaj nplaum zaj duab xis tau lees paub los ntawm ntau yam kev lag luam, thiab nws kuj yog cov yam ntxwv ntawm kev tiv thaiv ib puag ncig uas tau siv dav. Kev tsim thiab ua cov nqi ntawm tus kheej nplaum nplaum yog qhov tsawg, tab sis nws qhov kev tiv thaiv ib puag ncig yog qhov tseeb tsis piv rau cov nplaum nplaum kub yaj.
3. Qhov sib txawv ntawm txoj kev siv: Kev siv cov nplaum nplaum nplaum nplaum nplaum feem ntau yog nyob ntawm lub tshuab sib xyaw kom sib xyaw cov ntaub ntawv. Tus kheej-nplaum nws tus kheej muaj qhov qis melting point thiab yog kua, uas yog ib qho nyuaj rau ua rau lwm yam duab. Txoj kev "brushing" feem ntau yog siv thaum siv cov kua nplaum. Qhov tsis zoo ntawm txoj kev no yog cov kua nplaum zoo li thaiv qhov pores ntawm cov ntaub, ua rau airtightness.
